The Messerschmitt Me 262 Swallow (or Stormbird) has got to be one of the hottest looking aircraft ever designed. That shark-like fuselage not only looks menacing, it's also an aerodynamically well designed lifting body. Fortunately due to lack of high temperature resistant alloys and quality control problems arising from the Nazi's use of slave labor, the Me 262 had a lot of mechanical problems. Its Junkers Jumo 004 Turbojet engine had a time between overhaul interval of less than 50 hours. Mostly this was due to the wartime shortage of nickel alloys which would have enabled them to manufacture turbine blades that were more heat resistant. The materials used were not much better than common steel and were prone to stretching and cracking. In today's turbine aviation engines if you lose a compressor blade it might take out one or more blades behind it and keep running, although with a good deal of vibration and lessened power. If a Junkers Jumo 004 turbojet lost a compressor blade, it almost invariably led to a catastrophic cascading failure with the turbine shedding more and more blades in a domino effect until the engine literally blew apart. Interestingly enough the Arado 234 bomber which used the same engines had much fewer problems. The difference with the Arado 234 was that after takeoff the throttles were set to a cruise position and generally left there until landing. This made for less variations in operating temperatures and RPMs resulting in fewer compressor blade cracks and failures.

When the Junkers Jumo 004 turbojets were operating properly they were unbeatable and uncatchable. They were most vulnerable at takeoff and landing. The Me 262 did not have the complicated fuel management that today's gas turbine engines have. If the pilot advanced or retarded the throttles too quickly he risked over or underfuelling the engine causing a flame out and total power loss. The engines were also sensitive to angle of attack changes. If the airflow deviated much from coming straight into the intake, such as in abrupt maneuvering, the airflow could be disturbed enough stall the compressor, flaming out the engine.
